CRT fizzing out

Clarifications

Disconnect and get a new monitor, if it is new send it back for a free repair.
Be careful it could cause a fire.

Please post back if you have any more problems or questions.

Being a PackardBell I'd have put a bet on 10 months.

As Peconet says, something is obviously shorting out and after 10 years of service, I'd give it a decent burial before it cremates itself when you are not around.

[b]DO NOT attempt to open the CRT casing to have a look! The latent voltage inside a Cathode Ray Tube is sufficient to kill you![/b]

The Tripler is starting to fail. This is a Electronic Device that is between the Circuit Board and the Neck of the CRT that as it's name suggests triples the Power into the CRT.

Over time a build up of carbon occurs on these which causes a Short Circuit to happen hence the Sizzling sound followed by a black screen when the Tripler overheats and stops working.

You can have this replaced by a Qualified Technician but owing tot he age of the monitor you would most likely be better off replacing the monitor with something newer that has a better resolution and a smaller Pixel Size. You'll get a sharper picture and better resolution. Also you'll get better color differentiation which is important if you are doing any form of Graphics work.

I would advise against attempting to repair the unit yourself as there is enough power inside one of these Monitors to kill you without a second thought. I'm prepared to repair almost anything electrical but I do draw the line when it comes to CRT Monitors and TV's. It's way to easy to kill yourself without trying.

Before it starts a fire.

Cut the cord off before you dispose of it. That way no one else will be tempted to use it.

You got your moneys worth out of it.

You need to clean out all the dust bunnies with a vacuum and a long handle one inch wide artists brush, wooden handle only. Pay particular attention to the large red colored wire that goes to the side of the CRT(big tube) and the other end to a large colored transformer. Also clean what looks like a metal fence around that same area. Caution is prudent and never touch the wire or either end with a bare appendage. Very high voltages are present, they may not kill you but certainly knock you on your butt. If the paint brush has a metal end holding the brush hairs in place, wrap it with tape to isolate it and prevent it from shorting or conducting any voltage. Dust it briskly with the brush while keeping the vacuum cleaner head, again plastic nozzles, never any metal, close to the brush while dusting. Put it back together. If it still sputters and sparks, toss it or donate to your nearest school's E-WASTE fund raiser. Get tourself a nice LCD for an early Christmas gift.
